TYPE-WRITING- MACHINE.

Patented July 21, 1914;

Application led November 4, 1919. Serial No. 590,635. l

To all 'whom it may concern;

Be itiknown that I, SIGMUND Sonrrn, a subject of the King ofHungary,'res1d1ng in the borough of Manhattan, city 'of New York, in thecounty of New Yorkand State of NewYork, have invented certain new and:sol

useful Improvements` in. Type-riting Machines, of which the followingvis a speclcation. Y Y,

The presentinvention relates to an improved means in a typewritingmachine for shifting the platen with respect to the paper guide-tolpermit of correct and easy intem of key controlled leversvis eliminated,

so that the parts may be few in number, and

of simple construction.` The mechanism is 30l operated directlvby meansof a. wheel or similar device on the platen shaft; which,

in certain forms of the invention, maybeone ofthe hand Wheels commonlyfound at each end ofthe platen shaft. There is Ano. delay or movement ofthe parts aftr'the.

platen is positioned, to unlock the platen,

before the shifting of the platen is commenced; the' shift-ing commenceswithout any preliminary unlocking movement.

unlocking 'and' shifting movements are re`- solved into a simplerotation of the platen relatively to the eccentric or other device whichis used for shifting the same.

I also provide a simple and eective device for preventing shift of theplaten ex cept when the same is in such 'position that the shiftingmechanism must operate to throw it in the proper-direction. i

In .one form of the invention, a sleeve with' eccentrics attachedthereto is mounted 4to turn on the platen axle, the latter journaledinthe platen frame and carrying the usual hand Wheels for rotating it.The ec-v centrics are seated in openings formed in,

a clasp Iand the like at-A In a l form of the invention hereinaftershown the" platen ends eccentrically of the platen to shift the platentransversely of its axis when the eccentrics are rotated relatively to'the 1 platen. .The platen is normally rotated with' vthe platen axle bymeans of a disk fixed tothe be shifted transversely ofthe axle when the.

eccentrics are `rotated in the platen ends, a hand wheel on said sleeveforming a means eoA for rotating the eccentrics The eccentrics arenormally prevented from rotating in the platen and thereby shifting thelatter, by means of a pin projecting from the end of `the platen into acircular opening formed in a platev onthe platen frame, and therebypreventing outward movement of thepin except when the latter is broughtopposite a slot forming an extension of the circular opening. In anotherform of the invention, the eccentricsare rotatable on the platen toshift the latter by means of a hand wheel connected toa sleeve loose onthe platen axle and movable endwise on the axle into clutchingengagement .with the eccentric-V carrying sleeve. 4When the said handwheel" 'han -wheel is prevented from being moved inward to `connect saidclutch by a plate or lcollar on the platen frame, except when the sleevehas been rotated V to bring a pin orprojection lthereon opposite a-notchin said collar, so' that the eccentrics are adjustable `to shift theplaten only Awhen the platen and axle have been rotated vtoapredetermined position.v

Other. objects and tionwill hereinafter appear.

In the accompanying' drawing, Figure l is a view inperspective of theplaten and 'the means for preventing shift of the platen until the sameis turned to proper position. Fig. 4 is a View of the platen and platenshifting mechanism, looking at the right hand end of the platen, theparts being features of the inven ino Ahand end of the platen forshifting` and driving the platen; Fig. 7 is a detail view show- 'l bcertain of the parts of the apparatus shown in Fig. 6. l Y

Referring to the forni Of the invention 4shown in Figs. 1-5 included,the platenA shaft 1` is shown as having attached to the ends thereof theh and wheels 2 and 8. Also fast to the platen shaft is the line-spacingwheel 4f which is engaged in the usual manner by a pawl 5 to effect theline spacing movement of the platen 12. The platen is suitably mountedon the platen frame, a portion of which is shown in dotted vlines at 6in Fig. 2. 4The end lates 7 and 8V of the platen are shown as tted uponeccentric disks 9 and 10 by means of which the platen Yis supported onthe platen shaft. The eccentrics 9 and 10 are not, however,

fast to the shaft, but are fast to a sleeve 11` within which the shaftis fitted and which is adapted to be rotated relatively to the shaft forshifting the platen, by means of the eccentrics, transversely of theshaft. For convenience in assembling, the sleeve 11V is shown-in twoparts, one part 11il of which carries a wheel 13 by means of which thesleeve is rotated relatively to the shaft. The eccentrics are secured tothe sleeve by means of set screws 14, and in order that the two sectionsof the sleeve may turn together, the right hand eccentric is made fastto both sections by means of two set screws. Fast, by means of a setscrew 15, to the left hand end of the shaft, against the end plate 7 ofthe platen, is a plate or disk 16, which enby means of slots 17 and 18in the disk with pins 19 and 2O carried by the end plate 7, i such amanner that when the shaft with the disk 16 is rotated the latter actsupon the pin 19 or the pin 20, (according -to the direction of rotationof the shaft), to rotate the platen. The slots 17 and 1S arese1iiicircular in form to permit of the shift of the platen with thepins 19 and 20, when the eccentrics are turned relatively to the platenby means of the hand wheel 13. The plate 16 and the flanges Q1 on theeecentrics prevent longitudinal displacement ofk the platen.

ItA is desirable to prevent shift of the platen except when theeccentrics arein one angular position, indicated in any suitable manneras by means of mark 2201i the face of the platen, said positionpreferably being such that the platen, when shifted, will be carriedaway from thev paper guide. The platen with the eccentrics is thereforeturned to bring the mark 22 ,to said angular position before hand wheel13 is `turned to alined.

shift the platen, which position may be indie platen at other times,there is attached to the platen frame 6 a plate having a centralcircular opening 2lithrough which the platen shaft extends. The pin 20is not of suihcient length to reach the face of the plate 23, but thepin 19 is extended beyond the face of the disk 16 aiidenters the openingZet in the plate 23. The opening 24 is of such diameter. that the pin 19may be turned therein, around the shaft 1 as a pivot, when the disk 16is revolved with the platen. The periphery ofthe opening 24,

however, closely embraces the path 'of niovei ment of the pin 19v so asto prevent shifting of the platen except when the angular position ofthe platen is such that the pin 19 registers with a slot 25 in theplatev 23, as shown in Fig. 3. When, by means of the mark 22,

'pin 19v has been brought to the Fig. 3,

position, the platen may be shifted by the eccentrics, and the pin 19,movingwith the end plates 7 and 8 of the platen and following its ownslot '717, enters the slot 25 in the plate 23.

The norinalfposition of the parts is shown in Fig. 1.` The sleeve 11which carries' the eccentrics is not locked to the shaft 1 but snuglyengages the same. of the platen embrace the eccentrics sufficiently.closely to i prevent play or loose movement between the parts, but notso tightly as to offer appreciable friction to relative rotation of theparts. When the parts are in normal position and the platen shaft ismoved by the line spacing wheel or by the hand wheels, the movement ofeither of these is transmitted to the plate 16. If the movement of thehand wheel 2 is in the direction of the arrow (see Fig. 1),the plate 16,bearing against the pin 19 at the end of the slot 17, carries with itthis pin and the platen. If the rotation is in the opposite direction,it is the pin 20 against which the plate 16 bears to rotate thc platen.The ecceiitricity of the eccentrics is not largeandA there is noleverage exerted by the plate 16 which would tend to causo the saine toslip on the eccentric and thereby be shifted. The

.pin 19 furthermore, when bearing against they plate 23, positivelyprevents the shift of the platen during the normal rotation of theparts. The parts, therefore, ii'rove as a unit either backward orforward under normal conditions.

' "When it is desired to shift the platen, and

the parts are in the position shown in Fig. 3

so that such shifting is possible, the hand wheel 3 is held againstrotation, and the wheel 13 with the sleeve 11 is rotated in thedirection of the arrow on the wheel 13 in Fig. `1. The movement of thesleeve 11 is For preventing` the shift of the The end plates 7 which pinnormally engages the sleeve 32.-

transmitted to the eccentrics, and the plate 16 being held stationary toprevent rotation of the platen, the latter is shifted bodily on theeccentrics from the Fig. 4 position to the Fig. 5 position, so as tomove the platen away from the paper guide 26 and feed rolls 27. The pins19 and 20 are thrown by this movement to the other ends of their slots17 and 18, and, by engagementwith the endv walls of these slots, serveas-stops-to limit the trhrow .of the-platen. The'paper 28, with clasps29 or the like, having beeninserted and positioned,the platen isreturned to normal position by reverse movement of the Wheel 13, thehand 4wheel 3 being held dur'- ing the returnmovement by the operator.

The return movement to normal position is In the form of the inventionshown in Fig.y

6 the wheel -13 is dispensed with, and the hand wheel 2 is mounted sothat it may be disconnected from the platen shaft and connected tothesleeve 11.

3, which 'remains connected to the platen, and turning the handwheel 2,

which has been connected to the sleeve.- In Fig. 6 the plate 16, havingits pin and slot engagement with the platen, fis, for convenience ofillustration, not shown, but these parts are,

nevertheless, present, and perform the same functions as heretoforeascribed to them. Instead of Athe extension 11a of the sleeve with itswheel 13, the' sleeve in Fig. 6 terminates at the eccentric 10, and thelatter carries, in addition to the lflange 21, one member 30 of a clutchfor locking the sleeve and eccentrics to vthe hand wheel 2 for 'rotationwhen the platen is to be shifted. The other member 31 ofthe clutch,which is normally disengaged from the clutch member .30, -is carried bya sleeve 32 to whichhand wheel 2 is xedly attached by means of a set-screw 33. The hand wheel 2 is, however normally connected to the shaft1, so as to rotate thel latter, bymeans of a pin34 on the shaft,

Sleeve 32 has,.however, abayonet Joint engagement with the pin 34 on theshaft so `that by forcing the hand wheel 2 toward the 69 -theclutchmember 31 into'engagement with platen, the sleeve maybe moved-to bringthe clutch member- 30. When the sleeve with the hand wheel 2 has thusbeen moved, the

pin 34 enters that part ofthe bayonet jointj slot 35 which permits'thehand wheel 2 to be this positionof parts The platen may` then be'shifted by 'holding the hand wheel pressed toward the platen,

trics, relatively to the shaft 1, to which lat-' ter it will beremembered, the hand wheel 3 and plate 16 are fast. This relative'turning movementI therefore causes `the eccentrics to be turnedrelatively to lthe platen, and the latter to be shifted as described inconnecf tion with Figs. 1 to 5 inclusive. After the turning of thesleeve 32 on the. shaft has been commenced, the slot 35 holds the pin 34so that the 'clutch members cannot disengage, and'pressure on the handwheel 2 i s no.longer necessary.4 The f relative turning movement of theparts, and the throw of the platen, isdetermined by the pins 19 and 20engaging the ends of the slots 17 -and 18 (see Fig. 5) The 'pin 34 mayhowever by engagement with the end walls of the s lot 35 serve thispurpose. When the platen has been returned to normal position so thatthe pin 34 may enter .the olfset portion-of the slot 35, a coilcompression spring 4'0 throws the clutch member 31, and-with it thesleeve 32 and hand wheel 2, to normal position and the hand wheel 2 isagain locked to rotate with -the shaft 1.

A device 23 has hereinbefore been de:

lscribed for preventing shift of the ,platen Aexcept when the eccentricsare in one position, suitably indicated asby a mark 22 on.

the platen. This same device may be used in connection. with shiftingmechanism shown in Fig. 6, but in Fig. 6 there. is shown another devicefor thesame purpose. This vlatter device comprises -a disk or'collar 37,attached to the frame member 36. .and em'- bracing the clutch member 31.On the member 31 is a pin 39, and at one point of the collar 37 isanotch or opening 38. Unless the platen shaft with the platen and withthe clutch member 31 is turned to a position to bring the pin 39opposite the notch or open:

ing 38, the clutch member 31 cannot Abe moved into engagement with theclutch member 30,. because upon any effort to so move the clutch, `thepin '39 will strike the collar plate. 37, and the shift of the clutchmember thereby be stopp'cd. When however the platen is firstrotated tocorrect position with the pin 39 registering wit-h'the opening 38, andthe'hand wheel is thereafter the pin 39 passes through opening 38, andtheclutch members come ltogether, permitting the shift of the platen.

A' rsum of the operation of the invention as shown in Fig. 6 is asfollows: The platen roll and b oth the handwheels and eccentrics i.

being locked to the shaft 1, the same are all turned by either handwheeluntil the `pin 39 lies opposite the opening 38 in the'framelcarriedplate 37. The handle 3 is then held stationary and the handle 2 ispressed against the action of spring 40, until clutch inembers 30 and31; engage; At this time pinr 'of slots 17 and 1S to stop the shift-ingmovement. The paper being inserted, the inovenient is reversed until thepins 19 and 20 engage the lower ends of the slots 1 7. and 18, and thepin 34: in position to permit the spring 40 to throw back the clutchmember 31' With the sleeve 32 and handle 2 to normal position, againlocking the handle 2 to the shaft l, by means of the bayonet joint, anddisenga-ging the handle 2v from the eccentrics.

It Will be noted from the foregoing that no key operated lever system isrequired to `effect the unlocking and shifting of the platen withrespect to the shaft. lt Will also be noted that the moment the relativerotation of the parts commences, the shifting of the platen alsocommences so that there is no preliminary unlocking movement. lt will beseen that the platen normally rotates Withlthe shaft.

The shaft and the platen, by reason of the eccentrics, are in continuousengagement.

The invention has been shown in tWo forms only, butA it is obvious thatall or a number of the features of the invention may be embodied invariousotlier forms Within the scope ofthe invention.
